Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

As shown in fig. 1, the pneumatic turnover platform includes two single-side rotary bridges 10 in axial symmetry, a gap is provided between the two single-side rotary bridges 10, and the two vertical single-side rotary bridges 10 rotate 90 ° to form a horizontally arranged working platform. The pneumatic overturning platform can be arranged above an anode furnace mouth, when the anode furnace needs to be maintained, the two vertical unilateral rotary bridges 10 rotate by 90 degrees to form a horizontally arranged working platform, and workers can perform maintenance operation on the horizontal working platform; after the maintenance operation is finished, the one-side rotary bridge 10 in the horizontal state rotates for 90 degrees, so that no obstacle exists right above the anode furnace mouth, and the normal operation of the anode furnace is not influenced. Wherein the dashed part in fig. 1 is a single-sided swivel bridge 10 after swiveling.

As shown in fig. 2, the unilateral rotating bridge 10 includes a rotating frame 11, a supporting platform 12 fixed on a front section of the rotating frame 11, a cylinder 14 disposed on a rear section of the rotating frame 11, and a baffle 15 for blocking a rear end of the rotating frame 11 to enable the supporting platform 12 to be in a horizontal state, a hinge 13 is fixed on a middle section of the rotating frame 11, the cylinder 14 is used for driving the rotating frame 11 to rotate around the hinge 13 by 90 °, and the baffle 15 is located above the rear section of the rotating frame 11. The cylinder 14 can drive the revolving frame 11 to rotate around the hinge 13, when the horizontal supporting platform 12 is driven by the cylinder 14, the revolving frame 11 rotates around the hinge 13 by 90 degrees so that the supporting platform 12 is in a vertical state, and a very large space exists between the two supporting platforms 12 in the vertical state, so that no obstacle exists right above the anode furnace opening, and the normal operation of the anode furnace cannot be influenced. When maintenance work needs to be carried out, the vertical supporting platform 12 enables the revolving frame 11 to rotate by 90 degrees around the hinge 13 under the driving of the air cylinder 14, so that the supporting platform 12 is in a horizontal state, the two supporting platforms 12 in the horizontal state are just erected into a working platform, the baffle 15 is used for blocking the rear end of the revolving frame 11 to enable the supporting platform 12 to be in the horizontal state, and the baffle 15 is arranged, so that the revolving frame 11 can only rotate by 90 degrees around the hinge 13.

Further, to improve safety; guard rails 121 are fixedly arranged on two sides of the supporting platform 12 respectively.

Because the unilateral rotary bridge 10 in the vertical state usually needs to install other tools (such as bolts) to prevent the unilateral rotary bridge 10 from overturning, the bolts need to be pulled out before the fixed unilateral rotary bridge 10 rotates again, and the unilateral rotary bridge 10 is usually very high in height, so that workers are required to climb and then operate, and time and labor are wasted. Further, as shown in fig. 3, a water tank 20 is fixedly arranged on each of two sides of the supporting platform 12, a water inlet pipe 21 and a water outlet pipe 23 are arranged outside the water tank 20, the head end of the water inlet pipe 21 is communicated with the inner cavity of the water tank 20, and a first electronic valve 22 is further arranged at the head end of the water inlet pipe 21; the head end of the drain pipe 23 is communicated with the inner cavity of the water tank 20, and the head end of the drain pipe 23 is also provided with a second electronic valve 24. The water tank 20 has the same protection function as the guardrail 121; furthermore, when the support platform 12 is in a horizontal state, in order to reduce the load of the air cylinder 14, no water is present inside the water tank 20, as shown in fig. 4; when the supporting platform 12 is in a vertical state, the water tank 20 is also in a vertical state synchronously, at this time, the first electronic valve 22 is opened, the tail end of the water inlet pipe 21 is communicated with a tap water faucet, tap water is filled into the water tank 20 through the water inlet pipe 21, so that the self weight of the water tank 20 is increased remarkably, and simultaneously the tap water is accumulated at the lower half part of the water tank 20 in the vertical state, as shown in fig. 5, the gravity center of the whole one-side rotary bridge 10 is lowered, the gravity center of the one-side rotary bridge 10 is lowered, so that the one-side rotary bridge 10 in the vertical state cannot be turned over easily without other fixing devices, that is, a bolt is not required to be installed again by a worker to prevent the one-side rotary; when the one-side swing bridge 10 in the vertical state is required to swing again, the tap water inside the water tank 20 is drained to a designated position through the drain pipe 23 by opening only the second electronic valve 24. The water inlet operation and the water discharge operation of the water tank 20 can be controlled on the ground, workers do not need to climb to the position near the anode furnace mouth, and the operation is simple and convenient. Further, the water inlet pipe 21 and the water outlet pipe 23 are made of flexible pipes.

Further, the top of the water tank 20 is provided with an air hole 201 for balancing the air pressure inside and outside the water tank 20. The presence of the air hole 201 allows tap water in the tank 20 to be smoothly discharged during a draining operation.

Further, the supporting platform 12 is welded into a frame by using angle steel, and then patterned steel plates are laid to manufacture the supporting platform 12. The antiskid patterns are distributed on the surface of the patterned steel plate, so that the safety of the supporting platform 12 can be improved.

Further, in order to reduce the cost, the revolving frame 11 is made of channel steel through welding.

Further, to prevent the water tank 20 from rusting, the water tank 20 is welded from a galvanized steel plate.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
